Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01662 | $0.01662 |
| Opus 5 | $0.00831 | $0.00831 |
| Sonnet 5 | $0.00332 | $0.00332 |
| Haiku 4.5 | $0.00166 | $0.00166 |
Grade A, and why
aigon AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Aigon — Agent Instructions
Aigon is a spec-driven multi-agent harness. Keep this always-loaded file concise; read the linked references only when the task touches their area.
Start Here
aigon-cli.jsis dispatch only. Command handlers live inlib/commands/; shared behavior lives in focusedlib/modules.- Read the active feature/research spec before implementation and follow its scope and validation instructions.

Public Repository
This repository is public and everything in it ships to users. Never commit a literal credential, API key, or private roster — use placeholders or environment variables. .githooks/pre-commit blocks staged .env and *.local files; it is not a secret scanner, so the check is yours to make.
Target Repositories: Zero Opinion
Aigon owns only its feature/research/feedback process, specs, .aigon/ state, worktrees, branches, and managed sessions. It must not assume a target repo's language, package manager, test framework, build/deploy process, directory layout, or commit conventions.
This is load-bearing for everything under templates/{generic,docs,specs,prompts,skill-pointers}/, which is installed into unknown repositories. If template wording would be wrong in a Python monorepo, Rust crate, Go service, or static site, generalise it. Per-worktree setup is operator-declared through worktreeSetup; Aigon does not detect a stack or inject install commands.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
